SPECIFICATION forming part of Letters Patent No. 534,718, dated February 26, 1 895. Application nea october 27,1893. Seriana. 489,299. (No mada.)

To a/ZZ whom it may concern.-

Beit known that LMILTON G. JOHNS, a citizen of the United States, residing in Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain Improvements in Discharge-Pipe Protectors, of which the following is a specification.

This invention relates to devices for preventing the entrance into the escape-pipes of basins, bath-tubs, urinals and the like of matter liable to close those pipes; and the object of the invention is to protect the escape-pipes from the entrance of such matter and at the same time prevent the entrance to the same from being clogged u p.

The invention consists in the construction and combination of the several parts, as hereinafter fully described and then specifically pointed out in the claims.

The invention is illustrated in the accompanying drawings, which form a part of this spccication, and in which- Figure l is aside elevation of an inner protecting tube, and Fig. 2 a similar View of an outer protecting tube fitted over the same. Fig. 3 is a top plan view of the outei` protecting tube. Fig. 4 is a side elevation of the tubes, showing the cap fitted over them. Fig. 5 is a vertical section through the parts as shown in Fig. 4 and of a basin to which the protecting tubes are attached. Fig. 6 is a side elevation of a modified form of protecting tubes, and Fig. 7 a similar View of the lower ends thereof, a portion of the outer tube being cut away.

Similar letters indicate like parts throughout the several views. Y

Referring to the details of the drawings, A indicates a section of the lower portion of a basin, and B the escape-ppe having its upper end threaded internally, as shown at b.

D indicates a perforated protector tube ex- A tending upward from the bottom of the basin and opening into the escape-pipe and having the upper end closed. On its lower end there,

is a base D', which forms a shoulder, d, around the tube; and below shoulder d and around the base there is a horizontally projecting flange, d. Below flange CZ is an externally threaded extension, d2, of the base that is screwed into the threaded end of the escapepipe.

E is an external protector tube fitting over tube D, and it is sufficiently large to leave a chamber, O, intervening between the two. Tube E has larger perforations, e, than those, di', of tube D; the perforations of the two tubes being, preferably, in different Vertical planes. Around the bottom of tube E there is an inwardly extending fiange e', which rests upon shoulder d of the base with its inner edge bearing against the periphery of tube D.

In operating, the outer tube E prevents the passage of the larger obstructions which may be thrown into the basin, while the inner tube D prevents the passage into the escape pipe of any matter which might obstruct it and which' has passed through the perforations of tube E. By the use of these tubes the water will be permitted to escape so long as the obstructions do not entirely clog the top and sides of the outer tube andV fill the chamber interven.

ing between it and the inner tube. When 0bstructions accumulate in that chamber they can readily be removed by raising the outer tube E; and the interior of tube D can be cleansed by unscrewng it from the escapepipe.

When the flow of water through the protector tubes is to be prevented the close cap H is placed over the protector tubes,its lower end resting on liange d. On the top of the cap there is a ring or eye, h, by which a chain can be attached for securing it to the basin.

The coupling between the protector-tubes and the escape-pipecan be lowered so that the lower perforations in said tubes may be on a line with the bottom of the basin.

I do not confine myself to the details of construction shown and described, as it is evident that many changes may be made therein without departing from the spirit of my invention. Neither do I restrict myself to any height or configuration of the protector tubes.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is

I. The combination, with the escapepipe of a receptacle for liquids, of an Vupwardl y eX tending perforated protector engaging the escape-pipe, and an outer perforated protector fitting over said protector engaging said escape-pipe and having an inwardly projecting flange bearing against the periphery of the IOC latter, substantially as' and for the purpose specified.

2. The combination, with the escape-pipe of a receptacle for liquids,of an upwardly extending perforated protector engaging the escape-pipe, a shoulder formed by the base of said protector, and an outer perforated protector fitting over said protector engaging the escape-pipe and resting on said shoulder, the outer protector having an inwardly projecting flange bearing against the periphery of the inner protector, substantially as and for the purpose specified.

3. The combination, with the escape-pipe of a receptacle for liquids, of a perforated protector having a threaded extension engaging a threaded opening of the escape-pipe, the

pose specified. l
